I think it's still too early to make such conclusions. Some poaitive movements are present on the market but it's too soon to call that bull run. To my opinion we would need constant price rise of few weeks or even months in a row to make the conclusion that we have left bear and entered into bull phase. Many are disappointed with 2018 and they are very eager for 2019 to be successful year for Bitcoin but it takes a little time and patience.
Yes, I agree, it is too early to make conclusions like this topic, because we know that 2019 has just begun, so that there will be a possibility that prices will fluctuate again, I would rather not give predictions that fast.
